ABB Totalflow I/O Configuration in PCCU32
Key Takeaway
How to configure analog, digital, pulse, and temperature I/O on ABB Totalflow XSeries devices in PCCU32.
Quick Answer
Totalflow I/O is configured in PCCU32 under the I/O section of the device tree. Set input types per channel (4-20mA, voltage, RTD), assign engineering unit ranges, and link I/O channels to flow calculation and automation applications.
Analog Inputs
- Input type selection: 4-20mA, 0-5VDC, internal transducer
- Engineering unit range assignment
- Filter and damping settings for noisy environments
- Dedicated DP and static pressure channels for flow applications
Pulse Inputs
Turbine meter pulse inputs configured with K-factor and frequency range (low-frequency for turbines, high-frequency for ultrasonic auxiliary outputs).
Temperature Inputs
RTD (Pt100, Pt1000) and thermocouple type selection per channel. Temperature compensation is critical for accurate flow measurement.
Linking I/O to Applications
Each I/O channel is assigned to a flow calculation application (AGA-3, AGA-7, etc.) in the application configuration screen. The application reads the I/O value directly by register address.

Frequently Asked Questions
Totalflow includes dedicated DP input channels that connect directly to the DP transmitter. The raw value is read by the AGA-3 application for flow calculation.
Yes. Expansion modules are added to the backplane. PCCU32 detects new hardware and makes additional channels available for configuration.
